Gets rather tedious
I've been playing about 5 minutes and are through the first level. It's just a point and click shooter. Yes, you shoot nuns. Whoopeeeeeeee. Nothing new.
How about pickups so you can buy or upgrade guns? What about armour, or health boosts? You're just shooting at nuns one way. A 360 instead of an arcade style would be harder to program (I think, never tried) but I would like it better.
